  Microwave Assisted Synthesis of Some Pyridine Derivatives Containing Mercaptotriazole and Thiazolidinone as a New Class of Antimicrobial Agents

  摘要：

  A fast and facile procedure for the synthesis of pyridomereaptotriazole 4a-e and pyridothiazolidinone 5a-e is being reported starting from diliydropyridine 1a-e. Subsequent oxidation with nitrating mixture (HNO3/H2SO4) produced the anticipated 2,6-dimethylpyridine derivatives 2a-e, which were subsequently condensed with thiosemicarbazide in ethanol to produce the key intermediate 2,2'-[4(4-substituted phenyl)- 2,6-dimethylpyridine-3,5-diyl]dicarbonyldihydrazine carbothioamides 3a-e. In the final step pyridomercaptotriazole derivatives 4a-e were synthesized by treating 3a-e in alkaline media. In parallel pyridothiazolidinone derivatives 5a-e were obtained by the reaction of 3a-e with ClCH2COOH/CH3COONa. All the reactions were carried out on microwave irradiation in good yield with short time. The structures of all the compounds have been confirmed on the basis of their analytical, IR, H-1 NMR, and Mass spectral data (Tables I and II). The potent antimicrobial effects of the synthesized compounds were also investigated.
